(A) Variances shall not be issued within a designated regulatory floodway if any increase in flood levels during the base flood discharge would result.
(B) Generally, the only condition under which a variance from the elevation standard may be issued is for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items in division (H)(1) through (11) of this section have been fully considered. As the lot size increases the technical justification required for issuing the variance increases.
(C) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(D) Variances shall only be issued upon a:
(1) Showing of good and sufficient cause;
(2) Determination that failure to grant the variance would result in exceptional hardship to the applicant; and
(3) Determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public or conflict with existing local laws or ordinances.
(E) Variances may be issued for a water dependent use provided that:
(1) The criteria of divisions (A) through (D) of this section are met; and
(2) The structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety.
(F) Variances may be issued for the reconstruction, rehabilitation, or restoration of structures listed on the National Register of Historic Places or the Statewide Inventory of Historic Properties, without regard to the procedures set forth in this section.
(G) Variances as interpreted in the National Flood Insurance Program are based on the general zoning law principle that they pertain to a physical piece of property; they are not personal in nature and do not pertain to the structure, its inhabitants, economic or financial circumstances. They primarily address small lots in densely populated residential neighborhoods. As such, variances from the flood elevations should be quite rare.
(H) When reviewing such applications, the City Council shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter, and the:
(1) Danger that materials may be swept onto other lands to the injury of others;
(2) Danger to life and property due to flooding or erosion damage;
(3) Susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(4) Importance of the services provided by the proposed facility to the community;
(5) Necessity to the facility of a waterfront location, where applicable;
(6) Availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
(7) Compatibility of the proposed use with existing and anticipated development;
(8) The relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
(9) Safety of access to the property in times of flood for ordinary and emergency vehicles;
(10) Expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and
(11) Costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems, and streets and bridges.
